Pier of Death

Went through a massive mud puddle on a bike ride today. I was speckled like a warbler's egg. And then found the dinner scene of a seabird. Looks like he stumbled along this pier-like structure that juts out into the coastal wetlands, cracked open the shell of whatever this was, oyster or clam, and sucked it right down to its mother-of-pearl inner walls. This is the same place I found a torn off wing. Seems like a lot of brutal nature goes on here.
